TO ALL WHOM IT MAY CONCERN:

Be it known that I, RICHARD McDOwELL, of Lambertville, in the county of Hunterdomand State of New Jersey, have invented a new and improved Axle-Box Cover; and I do hereby, declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the s ame reference being had to the accompanying drawings, forming part of this specification. I

I The object of this invention is to provide a cover to axle boxes of railroad cars which can be easily removed and replaced for cleaning, lubricating, and other purposes. Heretofore such covers have been generally screwed down, so thatit requires the use of a wrench to remove or replace the same, whereby much waste oftimc is occasioned As itis often of great importance that the cars on a train should be lubricated during a short stoppage at a station, it is evident that the tedious arrangement for removing and replacing the axle-box covers is not practicable, and that a device is required whereby it can be done with greater dispatch. My invention, which consists in the applicationto the cover or to the axle box, or both, of two or more pins or flanges fitting in recesses arranged to the opposite part, and catching over flanges provided on the same, permits of the easy and quick removal and replacing of the cover. In the annexed drawing my invention is illustrated-'1 Figure 1 being a front elevation of the same. I

Figure 2 is a portion of a side view of the axle box.-

Figure 3 is a vertical sectional view of the cover.

Figure 4 is a front view of the axle box, the cover being remove h Figure 5'is a rear or inside viewof the cover.

Similar letters of reference indicate like parts.

A is the axle box, which is otherwise constructed as usual. To the front projecting ring (1 thereof are secured two or more tapering flanges, 6, whereby tapering grooves, b, are made between 'the said flanges and the projecting front surface of the boxywhich fiangesfit in recesses arranged in the cover Bi The latter is made in the shape of a cup, of cast iron, or any other suitable material, its inner diameter being equal to the outer diameter of the ring a. On the inside of'the cover 13 are also arrangcd tapering flanges, a,

whereby tapering grooves, c ',-are left between the said flanges and the covering plate of B, and when the cover is to be secured to the box the flanges on the cover must beheld opposite to the, spaces between the flanges on the box, while the flanges on the box must he opposite the recesses or spaces between the flanges on the cover. When the cover is fitted over the ring a it is turned so that the flanges on the cover come behind the flanges on the box, and the more the cover is turned the firmer will it be held on account of the tapering flanges. The cover is operated by a handle, d, which is made heavy enough to counteract any tendency of the cover' to turn on the ring a and drop off, the said cover being so arranged that it tends by its weight to draw the cover further toward the thick end of the flanges b, as is indicated by its position in fig. 1.

It is seen that by this arrangement the cover may be easily removed and replaced and firmly held in the axle box.

What I claim as new, and desire-to secure by Letters Patent, is-

1. An axle box having a projecting ring in front provided with tapering flanges 6, receiving thecap B, with corresponding flanges 0, having an operating weighted handle d, in the manner described for the purpose specified.

2. The weighted handle (1, arranged on the cover B, for the purpose of holding the same in position, substantially as herein .shown and described. I v
